Description

Tall Oil/Maleic/Pentaerythritol/Polyethylene Glycol Resin is a synthetic resin produced by the esterification and condensation of tall oil fatty acids, maleic anhydride, pentaerythritol, and polyethylene glycol. This versatile polymeric material is engineered to provide excellent adhesion, flexibility, and compatibility in demanding industrial formulations. It is a critical component for manufacturers in the coatings, adhesives, and ink industries seeking to enhance product performance and durability. The compound is identified by CAS No. 66071-14-5.

Application

This multi-functional resin is designed for high-performance applications where its unique polymeric structure delivers key benefits.

• Industrial Coatings & Paints: Acts as a film-forming agent and modifier in alkyd resins, providing improved flexibility, adhesion to difficult substrates, and corrosion resistance.
• Adhesives & Sealants: Used as a tackifier and rheology modifier in hot-melt, pressure-sensitive, and structural adhesives to enhance bond strength and thermal stability.
• Printing Inks: Serves as a resin vehicle in gravure and flexographic inks, contributing to gloss, pigment wetting, and substrate adhesion.
• Polymer Modification: Employed as a plasticizer or compatibilizer in various polymer blends to improve processing characteristics and mechanical properties.
• Foundry Core Binders: Functions as a binding resin in sand cores and molds for metal casting processes.
